Hi,
The merit score needed for admission to B.Arch is 80.95. So, your admission will be difficult as they require higher scores.
Best of luck.

Hi, your score is not so good. You have not even scored 40% in NATA you but you can get private colleges in Karnataka.

First of all which college? And, second thing is that I believe you didn't pass the NATA exam, as it is below the eligibility score (if not, then don't mind). And second thing is, that with these scores in both JEE and NATA it is impossible to get admission in a government architecture institution. You may try for some private colleges like Amity University or Galgotias University.
